IMPROVEMENT m TRUSSES.

Specification forming part of Letters Patent No. 167,977, datedSeptember 21,1875; application filed June 14, 1875.

To all whom it may concern:

Be it known that I, JASPER N. BELL, of Fort Dodge, in the county ofWebster and State of Iowa, have invented a new and useful improvement inTrusses, which improvement is fully set forth in the annexedspecification, reference being had to the accompanying drawings.

The nature and object of my invention is a truss that will beselfadjusting, always supporting the pad A firmly against the person ofthe wearer. This result is accomplished by the combination,in a truss,of a hollow hemisphere of rubber, B,.=which contains a spring which canbe'changed at will, and attached to a belt, D, supporting the pad A, asshown in the vertical section, Figure l, of the accompanying drawings. v

The invention is further illustrated byFigs. 2, 3, 4, 5, and 6. Figs. 2and 4 are views of the rubber hemisphere B. Fig. 3 is a perspective viewof the pad A, showing the projection H; and Fig. 5 a view of the springZ. Fig. 6 shows the interior spring in position.

I construct my truss as follows: I first provide an elastic belt, D. Tothis I attach the hollow rubber hemisphere B, which supports the pad A.The pad Ais made slightly concave on the surface, which comes in contactwith the person of the wearer, for the reason that it will keep itsposition better than a plane surface. I also provide a spring, Z, whichisplaced in the cavity of the rubber hemisphere B. The object is tofurnish a support to one side of the rubber hemisphere B, in case thewearer desires the pad A to stand at an angle to the belt' D.

It will be readily seen that when the spring Z is placed in position thecurl in the spring, and a part of the same, rests against the inside ofthe hemisphere B, thereby supporting that side, and giving it a greaterpower of resistance than the opposite side. The spring Z is movable, sothat the wearer can adjust the truss readily.

I further provide a short leather belt, 0, one end of which is fastenedto the pad A,

and the other to the main belt D. The belt 0 supports the hook E, towhich is fastened the elastic belt G by the ring F. The belt G isextended under the leg, and is fastened to the main belt D on the backof the wearer.

The belt D extends around the body in the v arranged in differentpositions to produce a greater pressure upon any side desired, all asand for the purposes specified.
